The role and maintenance of air compressor in HZS25 concrete mixing plant

Generally, the stationery concrete mixing station must be equipped with an air compressor. What is the role of the air compressor on HZS25 concrete mixing station? The air compressor provides pressurized air. This part of the air is used to open the butterfly valve of the cement, fly ash and other storage tanks, open the discharge door of the mixing main unit, etc., and simply provide power. In addition, some of the mixing main discharge doors are not air but hydraulic force, There are several advantages to using air instead of hydraulically open air: 1. The raw materials are easy to obtain, unlike the hydraulic system, the hydraulic oil needs to be replaced; 2. The maintenance is simple; 3. The action is simpler and clearer than the hydraulic pressure. The advantages of the air compressor are easy to maintain and master.

Maintenance of the air compressor of precast concrete plant: discharge the condensed water in time, open the drain valve under the gas storage tank after shutdown, and periodically replace the lubricating oil by condensing the water. Generally, it is determined according to the running time of the air compressor. Replace the oil with hours or 4 months.

The air filter of the concrete mixing station is regularly cleaned of the air filter element. Because the filter element is dirty, the air entering the compressor cylinder is excessively dusty, accelerating the wear of the cylinder and the piston ring, and is easy to form carbon deposits sealing; in serious cases, it will cause pulling cylinder and helium gas, causing pollution of lubricating oil and affecting lubrication effect; when helium is exhausted, oiling will occur, the gap between cylinder wall and piston ring will be too large, and the lubrication will be polluted. The oil will break into the compression chamber and form an oil mist that will contaminate the compressed air.
